[1]} reported that the cluster contains gas with an extremely wide range of temperatures and a wealth of structure. They also reported a discontinuity at \(\sim \) 30\(^{\prime \prime }\)  (\(\simeq \)  41.5 kpc) in the southeast region from the southern cD galaxy. It is at nearly this same distance where we report an enhancement of radio surface-brightness, toward the two cD galaxies, showing a sharp feature. We aim to search an X-ray surface-brightness edge, i.e., the shock front that is coincident with the northeastern sharp edge toward two cD galaxies of the remnant radio galaxy.
In order to understand the gas physics at this region of the cluster, we have extracted the surface-brightness profile from two box-shaped regions, one encompassing the remnant radio galaxy (called “outside" here) and the other adjacent to it toward cD galaxies (called “inside" here) as shown in Figure REF  (in magenta). We extracted the surface-brightnesses and the spectra from these regions, which are displayed in Figure REF . A single temperature model with Galactic absorption and the abundance fixed provided a good fit to the spectrum.
